[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] like Figures 1-6As shown, the utility model provides a technical solution: a large-diameter drainage pipe lifting construction device, comprising a steel beam 1, an automatic clamping mechanism 2 is provided on the steel beam 1, an auxiliary lifting mechanism 3 is provided on the top of the steel beam 1, the automatic clamping mechanism 2 comprises a support arm 21, the support arm 21 is fixedly mounted on the outer wall of the steel beam 1, the support arm 21 is fixedly mounted on the end away from the steel beam 1, an inner support member 23 is fixedly mounted on the inner wall of the support frame 22, an inner support member 23 is fixedly mounted on the inner wall of the inner support member 23, a driving cylinder 24 is fixedly mounted on the inner wall of the inner support member 23, a sliding block 242 is slidably connected to the inner wall of the driving cylinder 24, an elastic member 241 is fixedly mounted on the inner wall of the driving cylinder 24, and the end of the elastic member 241 away from the inner wall of the driving cylinder 24 is connected to the sliding block 2 The outer wall of 42 is fixedly connected, and the side of the sliding block 242 away from the elastic member 241 is fixedly connected with the clamping drive rod 243, and the outer wall of the clamping drive rod 243 is slidably connected to the inner wall of the support frame 22, and the end of the clamping drive rod 243 away from the sliding block 242 is fixedly connected with the arc-shaped clamping plate 26, and the outer wall of the driving cylinder 24 is fixedly connected with the air pipe 25, and the gas is transported to the inner cavity of the driving cylinder 24 through the air pipe 25. The gas will push the sliding block 242 to slide in the inner cavity of the driving cylinder 24, and at the same time stretch the elastic member 241, and then the transmission of the clamping drive rod 243 can prompt the arc-shaped clamping plate 26 to move and fit onto the outer wall of the pipe, thereby completing the clamping process of the pipe, avoiding the problem of fixing the pipe by bundling, which will consume a lot of manpower, and improving the efficiency of pipe fixing.

[0029] As an implementation method in this embodiment, Figures 1-4 As shown, the automatic clamping mechanism 2 also includes a centralized square tube 27 and an arc-shaped bonding plate 29. The centralized square tube 27 is fixedly mounted on the top of the steel beam 1, and the arc-shaped bonding plate 29 is fixedly mounted on the bottom of the steel beam 1. The end of the air pipe 25 away from the driving cylinder 24 is fixedly connected to the outer wall of the centralized square tube 27. A valve 28 is fixedly connected to the left side of the centralized square tube 27. The output end of the external air pump is connected to the valve 28. Opening the valve 28 controls the operation of the external air pump, and can transport gas to the inner cavity of the centralized square tube 27. The gas can then pass through the air pipe 25 into the driving cylinder 24, which is convenient for clamping the pipeline. After the pipeline is hoisted into place, the control valve 28 is opened, and the reset elastic force of the elastic member 241 can drive the sliding block 242 and the arc-shaped clamping plate 26 to reset, so that the gas inside the driving cylinder 24 passes through the air pipe 25 and the centralized square tube 27 and is then discharged from the valve 28, thereby releasing the fixed treatment of the pipeline.

[0030] As an implementation method in this embodiment, Figure 5 、 Figure 6As shown, the auxiliary lifting mechanism 3 includes a lifting frame 33, the bottom of the lifting frame 33 is rotatably connected to a rotating table 32, the bottom of the rotating table 32 is fixedly installed with a connecting leg 31, the connecting leg 31 is welded to the top of the steel beam 1, the bottom of the inner wall of the lifting frame 33 is fixedly installed with a stepper motor 34, the output shaft of the stepper motor 34 is fixedly connected to the top of the rotating table 32, the top of the lifting frame 33 is fixedly installed with a circular connecting plate 35, the top of the circular connecting plate 35 is welded with a connecting frame 36, the connecting frame 36 is threadedly connected with a locking bolt 37, the number of connecting frame 36 is set to four, the inner cavity of a connecting frame 36 located at the top center of the circular connecting plate 35 is detachably connected to the main lifting ear 38, and the inner cavities of the other three connecting frame 36 are detachably connected to auxiliary lifting ears. The lifting lug 39 connects the main lifting rope of the crane to the main lifting lug 38, and the lifting rope branch is connected to the auxiliary lifting lug 39. If the main lifting lug 38 or the auxiliary lifting lug 39 is accidentally broken, this structure can still maintain the connection with the lifting rope, thereby improving safety. The threaded end of the locking bolt 37 can extend to the inside of the main lifting lug 38 or the auxiliary lifting lug 39. Through the design of the connecting frame 36 and the locking bolt 37, it is convenient to replace the damaged main lifting lug 38 or the auxiliary lifting lug 39. After the pipeline is lifted to the vicinity of the installation position, if the angle of the pipeline deviates greatly from the installation angle, the stepper motor 34 can be controlled to work, driving the rotating table 32 to rotate and the components at its bottom to rotate, thereby realizing the function of adjusting the angle of the pipeline, thereby avoiding the problem that the user has to make large adjustments to its angle after the pipeline is released to the ground.

[0031] Working principle: When in use, the sling is pre-connected to the main lifting ear 38 and the auxiliary lifting ear 39, and the structure is moved by the crane to force the arc-shaped fitting plate 29 to fit onto the pipe. Then, the output end of the external air pump is connected to the valve 28, and the valve 28 is opened to control the external air pump to work. The gas pushes the arc-shaped clamping plate 26 toward the outer wall of the pipe to complete the clamping of the pipe. The external air pump is then withdrawn and the valve 28 is closed. The pipe is then moved to the vicinity of the installation position by the crane. If the angle of the pipe deviates greatly from the installation angle, the stepper motor 34 is controlled to work to adjust the angle of the pipe, and then the pipe is released by the crane. After the pipe touches the ground, the valve 28 is controlled to open to release the connection between the structure and the pipe.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
